Neon sizes compute in Compute Units, where one unit is one vCPU with 4 GB of RAM, and an endpoint is configured with a minimum and a maximum rather than a fixed size; it scales between them according to load.
Two consequences follow for anyone measuring performance. A benchmark started right after a cold start runs on the minimum size and gets faster as the endpoint scales up, so the opening numbers are not representative of steady state and a warm-up phase is required. And max_connections is derived from the endpoint's configured compute size rather than from instantaneous load, so changing the size range changes the connection ceiling the application sees. Setting the minimum and maximum to the same value is the way to get a stable, comparable measurement.
